Abstract

THE PRESENT INVENTION RELATES TO AUDIO SIGNAL PROCESSING AND, IN PARTICULAR, AN APPARATUS AND A METHOD FOR AUTOMATIC MICROPHONE POSITIONING. AUDIO SIGNAL PROCESSING BECOMES MORE AND MORE IMPORTANT. IN PARTICULAR, SPATIAL SOUND RECORDING IS EMPLOYED IN A PLURALITY OF APPLICATIONS. SPATIAL SOUND RECORDING AIMS AT CAPTURING A SOUND FIELD WITH THE HELP OF MULTIPLE MICROPHONES SUCH THAT AT THE REPRODUCTION SIDE, A LISTENER PERCEIVES THE SOUND IMAGE AS IT WAS AT THE RECORDING LOCATION.
